Modifications and Enhancements

The modifications/enhancements for each service release are described next. This information is also available in the ReadMe file that is installed with the software. The most recent service release (build) contains all previous modifications.

Build 6.5.4

• Added an option to Rest Cell(s) Format in the Edit menu of the Stress Profile Explorer.
• The input for the probability of failure for the BX Information and Time given Probability of Failure functions in the Function Wizard have been changed to percent.
• Fixed an issue regarding the Arrhenius-Lognormal failure rate calculations in the Function Wizard.

Build 6.5.3

• Corrected an issue regarding the failure rate calculations for the Temperature-NonThermal life-stress relationship.

Build 6.5.2

• Fixed an intermittent issue regarding the integration of the Cumulative Damage life-stress relationship with a cyclical time-varying stress.

Build 6.5.1

• Added Weibull++ 7 support.

Build 6.0.12

• Resolved an occasional issue when calculating mean life for General Log-Linear life-stress relationship with the lognormal distribution.
• Corrected an intermittent error of not transferring proper stress column data to Weibull++ when more than one stress column was specified to be used. This also applies to the Degradation analysis.
• Added ability to include multiple stress columns (max = 8) in Accelerated Degradation analysis.
• Fixed an intermittent error when deleting sheets.
• Corrected an occasional issue which kept the points on the Use Stress Level Probability plot from displaying even though the option is selected.

Build 6.0.11

• Corrected an occasional issue in regards to the Cumulative Damage model that kept the parameters from being displayed.
• Do not allow to show data points on Life vs. Stress plot for Cumulative Damage.

Build 6.0.10

• Resolved an issue on the Life vs. Stress plot that kept the proper plot settings from being used while on a multiple plot sheet.
• Added the data points to be plotted along the pdf on the Life vs. Stress plot. The points can be toggled on/off via the Show Points option in the Plot Options menu. Added properties to the Plot Setup to account for the data points on the Life vs. Stress plot.
• Corrected an intermittent error which occurred in Monte Carlo when trying to set the Cumulative Damage relation.
• Fixed an issue which kept the newly created data sheet from having the proper default use stress level.
• Fixed an occasional issue which kept the points on the plot from displaying even though Show Points was checked.
• Corrected an intermittent issue where the use stress levels were not being properly updated for the selected data set.

Build 6.0.9

• Corrected error that kept the Plot All Stresses functionality of the Side-by-Side plots from working properly.
• Fixed an intermittent problem of not saving plot setup settings.
• After converting temperature values within a stress column, the data sheet is no longer calculated.
• Resolved an occasional issue when conducting calculations in the Quick Calculation Pad when Use Percent Values.
• Fixed intermittent error of not properly displaying var/cov matrix when using combination models.

Build 6.0.8

• Fixed an issue regarding Temperature-NonThermal confidence bounds on reliability.
• Corrected data entry error when entering values less than one while using international settings.
• Fixed an intermittent error which incorrectly setup the stress columns being used for calculations when selecting Temperature-Humidity.
• Resolved possible crash when displaying tooltip text for use stress button.
• For a multiple plot, corrected an interface issue which incorrectly displayed a list of available time-varying profiles when the model was not Cumulative Damage.
• Fixed an intermittent problem which kept the stress profile list from being displayed even if you right-clicked within a stress column when using Cumulative Damage.
• When deleting a stress column, any entered data for that column also gets deleted and the column header gets reset.
• Added a feature in User Setup to allow for large Beta values when conducting calculations with Cumulative Damage - Weibull.

Build 6.0.6

• Resolved intermittent issue when trying to plot while varying the third stress column or higher.
• Fixed an intermittent problem regarding the formatting of a copied and moved data sheet.
• Corrected an issue which occurred when transferring F/S data to Folio from degradation.

Build 6.0.4

• Enabled pasting on the demo version that allows for saving.
• Corrected intermittent issue in which the use stress is not being read properly while calculating using Cumulative Damage.
• Resolved an occasional issue of not creating proper data sheet.
• Fixed an intermittent issue which did not display the attached stress library when loaded.
• Added ability for the 3D-Plot to remember the auto scaling settings if they are changed by the user.

Build 6.0.2

• Resolved intermittent issues regarding the scaling on the Cox-Snell and Standardized vs. Fitted Value residual plots when using small axis values.
• Edited the line for zero on a Standardized vs. Fitted Value residual plot so that it is no longer linked to whether or not the legend is being displayed.
• Fixed an issue which occurred after changing the name of a data sheet and then trying to plot.
• Removed the ability to access the Quick Calculation Pad from a multiple plot sheet.
• Resolved an intermittent issue which occurred while generating an Auto Report while the auto scaling for the plot sheet was not selected.
• Fixed an issue regarding the x-axis title on a Life vs. Stress plot so that the default title is not used if the title specified is not equal to the application default value.
• Resolved an intermittent issue with the licensing on international versions of Windows.

Build 6.0.1

• Initial Release.
